What is the histological structure of liver?
The liver is a mixed gland surrounded by a thin capsule of connective tissue, the Glisson capsule, dividing the parenchyma into lobules and lobuli. The histological unity of the liver is composed of the liver lobuli, with classic, portal and acini conceptions.
What are the 4 tissues in the liver?
The normal liver contains typical connective tissue proteins (collagens, structural glycoproteins and proteoglycans) not only in vessel walls, perivascular areas and in the capsule, but they occur also in small amounts in the parenchyma, mainly in the space of Disse along the sinusoidal walls.
What type of tissue is in liver?
The liver has a thin capsule of dense connective tissue, and a visceral (inferior) layer of peritoneal mesothelium, and is divided into left and right lobes.
What is liver structure?
Structure. The liver consists of four lobes: the larger right lobe and left lobe, and the smaller caudate lobe and quadrate lobe. The left and right lobe are divided by the falciform (“sickle-shaped” in Latin) ligament, which connects the liver to the abdominal wall.
What are the 5 functions of the liver?
The primary functions of the liver are:
- Bile production and excretion.
- Excretion of bilirubin, cholesterol, hormones, and drugs.
- Metabolism of fats, proteins, and carbohydrates.
- Enzyme activation.
- Storage of glycogen, vitamins, and minerals.
- Synthesis of plasma proteins, such as albumin, and clotting factors.
What are the 8 segments of the liver?
|Four hepatic sectors||Eight hepatic segments|
|Segment I – the caudate lobe|
|Left lateral sector||Segment II – posterosuperior|
|Segment III – anteroinferior|
|Left medial sector||IVa – superior segment|
What is the structure of the liver and its functions?
The liver holds about one pint (13%) of the body’s blood supply at any given moment. The liver consists of 2 main lobes. Both are made up of 8 segments that consist of 1,000 lobules (small lobes). These lobules are connected to small ducts (tubes) that connect with larger ducts to form the common hepatic duct.
What is the structural and functional unit of liver?
The hepatic lobules are the structural and functional units of liver containing hepatic cells arranged in the form of cords.
What is a histological image?
Histopathology is the study of the signs of the disease using the microscopic examination of a biopsy or surgical specimen that is processed and fixed onto glass slides. To visualize different components of the tissue under a microscope, the sections are dyed with one or more stains.
